Before explaining in detail the present invention it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation, and it is not intended to limit the invention claimed herein be-' yond the requirements of .the prior art.

In the drawings I have shown, by way of example, three structures embodying my invention. Referring particularly to Fig. 1, the same represents a sink or wash basin comprising generally a horizontally extending face 20 in which there is formed a main or shallow basin W, said basin being surrounded at its four sides by said horizontal portion 20. The latter comprises in the finished sink a back ledge or shelf 2i and a continuous rim 22, 23; 2t merging smoothly into the shelf and all forming a co-planar horizontal surfacasurroundingthe main and sub-basins. In the bottom of said main basin 30 there is formed a second basin or fluidreceiving bowl 3!, which I term the sub-basin. It is an important feature of my invention, that the bottom of the main basin 30 extends around all four sides of said sub-bean 3|, the corresponding parts of said bottom being indicated by the characters 32a, 32b, 32c and 32:1. The back edge of the. horizontal portion 20 merges seamlessly into an upright or vertically extending splash-back indicated generally by the numeral so. The face 4! of said splash back .09 may be suitably embossed, such for example as indicated by the panel embossing 62. A desired number of suitable faucet and spout holes-l3, 48, is provided in the splash-back. At its top and ends the splash-board Ml is provided with rearwardly extending flanges such as 46, 45. and M, which flanges are in turn provided with narrow wall flanges 41, 48 and 49, respectively (see Fig. 17). The ledge 2! which extends between the main basin 30 and the splash-back 40 is made of such width as to permit its use as a shelf for such articles as. glasses and the like.' The continuous rim portions 22, 28 and 24 which extend around the front and sides of the main basin 3!! are preferably made somewhat narrower than the shelf ill. The horizontal rim portions 22, 23, 24 are turned'downwardly to provide a continuous seamless depending apron, the respective portions whereof being designated by the numerals 25, 2B and 21. The lower edges of said apron are-provided with a substantially horizontal, continuous inwardly extending flange such as indicated at 20. The bottom 32 of the main basin 30 is preferably made slightly sloping toward the sub-basin 3|, and it-is provided with a number of suitably disposed drain grooves or beads such as It, 33. In the structure shown in Fig. 1 the sub-basin 3! is located substantially in the middle of the hot- 'two groups at both sides of saidsub-basin 3i,

thus providing a double drainboard sink, with portions 82a and 82b of the bottom 32 serving as drainboards.

The bottom 32 merges seamlessly into the walls of .the sub-basin 8|, which sub-basinis made deeper than the main basin 3b., The bottom 34 of the sub-basin ti is made slightly sloping toward a drain hole 38, which hole is preferably located not at the centerof said bottom M, but closer to the back wall 38 of the basin. By virtue of this construction it is possible to locate the spout outlet directly above the drain hole 35 without requiring the use of a spout of excessive length or overhang from the splash-back to the fluid receiving bowl.

Referring to Fig. 3 there is shown in this instance a sink similar in part to the structure of Fig. :1, the sub-basin however being arranged to provide a so-called left hand drainboard sink. As shown in Fig. 3, the sub-basin 5i is arranged at the right hand side of the bottom 52 of the main basin to, there being a-narrow ledge 52b between the sub-basin BI and the right hand side wall of the main basin to, and ledges 52c and 52d formed by the bottom Ell. In other words, while in the previous structure the portions 32a and 32b extending at both sides of the sub-basin 3| are substantially symmetrical in the structure of Fig. 3 the drainboard portion 52a is similar to the drainboard portion 32a of the embodiment of Fig. i and is provided with beads such as 58, 53.- The narrow ledge 52b has a width preferablyv equal to that of the ledge 52c and ledge 52d.

Referring to the embodiment illustrated in Fig. 5, the structure herein shown is a left hand subbasin sink difieri'ng from the structure of Fig. 3 by the arrangement of the sub-basin Si in the bottom 82 of the main basin 89. As can be clearly seen in Fig. 5, the sub-basin 6| is arranged It will be clear in view of the foregoing, that my novel sink many advantageous features not found in previous structures. Provision of the wide back ledge or shelf which is a continuation of the top horizontal surfaces of the surrounding rim provides a conveniently located flat horizontal surface upon which articles, such as glasses and the like, may be safely and conveniently placed without interfering with the use of the basin and drainboards. 0

Figs. '7 to 10, inclusive, illustrate preferred steps in the method of forming the sinks in accordance with the invention from a single sheet metal blank. In fabricating the double drainboard sink of Fig. 1 a single sheet metal blank I0 is placed in a suitable press and the central portion is preliminarily drawn to provide the sub-basin 3|, as illustrated in Fig. '7, this being accomplished by a suitably shaped dies. In a succeeding'operation the blank is operated upon in suitable dies to form simultaneously the main basin 30 and the drain beads 88in the bottom 32 thereof, as illustrated in Fig. 8. In the same or succeedin operationsthe subti may be re-struck line 16 (see Fig. 14).

stance, as indicated at 29. v

In addition to the foregoing steps in the formaand completed as to shape and depth, as well as embossed for the drain hole 35 asindicated-at 35a, and its bottom made sloping toward said embossed portion, as illustrated in Fig. 9. In Fig. there is shown a blank for the right subbasin sink after similar operations have been performed thereon. V

In accordance with the next preferred step in the method, the blank is preferably rough trimmed around its edges 1 I, and a suitable shape facilitating further forming operations is given to the corners I2, I2 thereof.

In the following operation the metal in rear of the upright back wall of the sub-basin 3| is formed or bent up along the line It, It (see Fig. 11), thus simultaneously forming the shelf 2| and the face 4| of the back panel or-splashboard 40 (see Fig. 12). For forming the top and end flanges 44,45 and E6 of the splash-back 40, the marginal metal of the upstanding portion'formed in the preceding operation is pressed rearwardly, substantially along the dotted line (Fig. 12), this being accomplished between suitable dies, the face 4! being preferably simultaneously embossed as at 42. The result of this operation is illustrated in Fig; 13, wherein the splash-back is shown provided with a continuous uninterrupted flange,

along its top and ends, the flanges at its ends merging seamlessly into the rear ends of the hor-' in the method preferably consists in forming thedepending apron flange. This is veifected by'pressing'or turning downwardly the marginal met al of the horizontally extending rim forming portion of the blank approximately along the dotted As can be seen in Fig. 15 wherein the result of this operation is illustrated, there is thus produced a continuous depending apron consisting of seamlessly merging portions 25, 2t and 27-, the real-most extremities of the portions 25 and 211 merging seamlessly into the lowermost extremities of the splash board flange portions t5 and M, respectively, such, for intion of the sink, succeeding forming operations are desirable to provide flanging along the lower edge of the depending apron, such as shown at 28 (see Fig. 18), and providing a continuous wall flange along the rear flanged edges of the splashboard til, comprised of mutually merging flange portions 31, 48 and 63 '(see Fi 17).

Fig. 19 shows the blank after the following operations of piercing and ofisetting the drain hole 35, and piercing and countersinking the faucet and spout holes 43, t3. I
